Subject [jira] [Commented] (MAPREDUCE-6201) TestNetworkedJob fails on trunk
Date Tue, 07 Feb 2017 12:33:42 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15855896#comment-15855896
] 

Peter Bacsko commented on MAPREDUCE-6201:
-----------------------------------------

We have to increase "yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage".
The disk checker turns the Mini cluster node status to {{UNHEALTHY}}. When we call {{client.getClusterStatus(true)}},
{{getActiveTrackerNames}} will return 0 because nodes are not in {{RUNNING}} status - see
{{ResourceMgrDelegate.getActiveTrackers()}}.
